WATER FILTER, HEATER, AND COOLER.

SPECIFICATION forming part of Letters Patent No. 630,327, dated August 8, 1899.`

Applicant inea Demtef 7, iets. serial No. 4693.543.

To @ZZ whom, it may con/cern:

Beit known that I, EDWIN S. OLOWER, a citi-` zen of the United States, residing at Philadelphia, in the county of Philadelphia and Statel Heaters, and Coolers, of which the following is a specification.

My invention relates to a new and useful improvement in water ilters, heaters, and coolers, and has for its object to provide an apparatus which may be interposed between the water-suppl y pipe and an ordinary domestic boiler and which in operation will raise the temperature of the supply-'water before reaching the boiler, will filter the water in passing from the boiler to the withdrawalfaucet, and at the same time cool the water during its filtration to nearly the same temperature as the supply-water.

With these ends i in View this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.`

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawing, forming a part of this specification, in which the apparatus embodying my improvement is shown in vertical section.

In carrying out my invention as here embodied I provide a cylindrical outer casing A, closed at both ends and having a supply-pipe B connected with the topthereofin order that the supply-water may be admitted at this:

point and permitted to flow downward and again pass from the apparatus through th'e pipe C, which leads to the domestic boiler. An inner cylindrical casing E is inclosed within the outer casing and is of such diameter as to leave a space F. This cylinder is secured to the bottom of the outer casing, and the return-pipe G enters the bottom thereof, and this return-pipe coming from the boiler is for conveying the heated water to the inner cylinder. -A pipe H leads from the top of the inner cylinderl and has one or more faucets l connected therewith for the withdrawal of the water, as occasion may require. The inner cylinder E is the filter proper, be-

water,

(lio model.)

Ving divided into compartments by the partitions J, K, and-L, the lower compartment M serving as a receptacle for the heated water iowing through the pipe G, the compartment N being preferably filled with cokeor other suitable material for filtering the water in its passage therethrough, while the compartment O is preferably lled with charcoal to further filter and purify the water in its passage to the pipe H. The partitions J, K, and L are perforated to permit the ready flow of this water. By this arrangement it will be seen that the supply-water flowing into the apparatus through the pipe B will be at its lowest temperature at the point of entry; but during its passage through the space F it will come in contact with the inner cylinder E and in so doingabsorb heat therefrom which has been imparted to said inner cylinder by `the uptlowing ofthe hot water from the pipe G.

The temperature of the supply-water being thus raised before it reaches the pipe O, it will pass to the boilerin the best condition for the still further raising of its temperature to the desired point. After being heated the 4water will then return through the pipe G to the inner cylinder` E and of course will be of the-highest temperature at the point of entering said-cylinder, while during its passage through the ltering material its temperature .will be gradually lowered by the absorption of heat therefrom by the inowing supplyas before set forth, until the upilowing water reaches the pipe H, when its temperatu re will be nearly, if not quite, the same as the supply-water at this point. This is a most desirable arrangement, since in a single apparatus theAsupply-water is heated before entering the boiler, after the manner of a feedwater heater for steam-boilers, while the hot water during its filtration is cooled, andthus delivered in the best condition for use. Another advantageV of-,my improvement is that the Water being heated before being nintroduced into the filtering-cylinder is far more susceptible to filtration than when at a lower temperature, and as the water has been heated to high temperature in the boiler all diseasegerms will have been destroyed, so that the Water delivered at the faucet will be both mechanically and chemically pure.

The cost of my apparatus is small, and, there IOO being no mechanism attached thereto, it is'eX- ceedingly durable. Having thus fullydescribed my invention, What I claim as new and useful isy l. A ilterng apparatus consisting or an outer casing, within the outer casing as to form a-space therebetween, a supply-pipe connected with the outer casing, a pipe for permitting the outflow of the supply-Water, this last-named pipe being connected With a boiler, a returnpipe leading vfrom the boiler to the inner cylinder, iiltering material located Within the inner cylinder, and a pipe leading from the top of the inner cylinder to one or more faucets,

-as specified.

2. In combination, an outer casing and an inner casing, the latter being divided into suitable compartments containing filteringv material, a pipe leading to the top of the outer casing, a pipe leading outer casing to a boiler, a return-pipe leadan inner cylinder so locatedv from the bottom of the ing from the boiler to the inner casing, and a pipe leading from ythe top of the inner casingvto Withdrawal-faucets, as specified.

3. A filter consisting of an outer casing and a cylinder located therein forming a spacev through which 'the supply-Water may IloW on its Way to the boiler, a pipe leading from this space to the boiler, a pipe leading from the boiler to the cylinder, and a pipe leading from the top of the cylinder to suitable faucets whereby the inflowing supply-Water Will be raised. in temperature before reaching the boiler, and the return-Water during its ltration will be cooled by the supply-Water,- as specified.

In testimony whereof I have hereunto afxed my signature in the presence of two subscribing Witnesses.
